@Charlie Hampton oh I now understand your predicament.

Not endorsing or commenting on "morally" whether or not big investment firms and P/E treat tenants right, but the same happens with individual landlords sometimes.

There are a lot of moral aspects to the landlording life, and it is such an important thing because we have such an impact on people's lives. what are your thoughts on this interesting topic?

Let's face it there is not one profession out there, military included, that doesn't have their share of people with very high moral standings and some with no morals at all.

My FICO score was hurt badly and I had numerous troubles getting financing on my properties.I am sure you get the morale of the story by now, and I hope my story help you not to make the same mistake...However, life goes on and I still need to deal with it to get my financing...

In sitting back and thinking on this I believe I have figured out a way to approach the situation in a moral and proper manner. 

There is also the process of gentrification to consider, from a moral perspective, but I guess flipping it incurs the same questions...

Moral of the story, there is risk, more than what is likely being sold by the OP's Seller or understood by the OP on his own merit.Is this a good deal?  

You do have a right to earn money, a moral obligation.
